you got the whole thing down pat, excellent impression of Jimmy's humour, and the whole 'hot-and-cold' thing they've got going, seriously AMAZING. I really enjoyed this, and this is the best (Of all 7 of them on this website, sadly..) Titanic 2020 fanfiction I've read (:

You could probably work on the grammar, like especially commas and the like a bit, but I honestly really enjoyed this and it's very accurate and believable in conjunction with the original novels.
